Which company owns MAC address prefix 50:4F:94?

MAC address prefix 50:4F:94 is registered to Loxone Electronics GmbH in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 50:4F:94 has a network interface built by Loxone Electronics GmbH.

What is the OUI 50:4F:94?

50:4F:94 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Loxone Electronics GmbH. It covers every address from 50:4F:94:00:00:00 to 50:4F:94:FF:FF:FF, or 16,777,216 addresses in total. It is also written 50-4F-94.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 50:4F:94:00:00:00 that is 50:4F:94 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is Loxone Electronics GmbH located?

Loxone Electronics GmbH is listed at Falkensteinstraße 6 Kollerschlag Upper Austria AT 4154 in the IEEE OUI registry entry for 50:4F:94. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does Loxone Electronics GmbH own?

Loxone Electronics GmbH holds 2 OUI prefixes in the IEEE registry, of which 50:4F:94 is one. A device made by Loxone Electronics GmbH could carry a MAC address from any of them.
